android - how to set Robotium test priority? -

i want set test cases in queue. runs alphabetic queue in run congiguration: android tests, how set robotium test priority?

for example want run @ first testsecond, , testfirst, how configure that?

public void setup() throws exception {        super.setup();        solo = new solo(getinstrumentation());        getactivity();      }       @override      public void teardown() throws exception {        solo.finishopenedactivities();        super.teardown();      }       public void testfirst() {}       public void testsecond() {} 

the priority based on characters. in other words, runs z.
